New Yorkers and tourists tempted to cool off during the current heatwave by plunging into the Hudson River have been warned: it’s never been more dangerous. Researchers at Columbia University reported Thursday that antibiotic-resistant bacteria was widespread in the river…

MRI fast track for Alzheimer’s diagnosis

A new approach to analyzing MRI brain scans could help speed up the diagnosis of Alzheimer’s and other degenerative diseases, according to research published to be published in the International Journal of Computational Science and Engineering. Clayton Chen of Taichung…

Stem cell research reveals clues to brain disease

(Medical Xpress)—The development of new drugs for improving treatment of Alzheimer’s and Parkinson’s disease is a step closer after recent research into how stem cells migrate and form circuits in the brain. The results from a study by researchers at…

Factor for impaired immune response in pneumonia identified

(Medical Xpress)—Macrophages, also known as scavenger cells, play an important role in defending against bacteria and pathogens by activating inflammatory processes. In cases of lung inflammation (pneumonia) caused by pneumococcal bacteria, this important immune response function is hampered and blocked…
